TL90 Digital Pitch Gauge – High-Precision Electronic Blade Angle Measurement Tool with Built-in Gyro Sensor & Auto-Reversing Backlit LCD Screen

The TL90 Digital Pitch Gauge is an essential calibration instrument engineered to deliver rapid, ultra-accurate pitch angle adjustments for RC helicopter rotor blades and aircraft propellers. Compatible with both flybar and flybarless rotor assemblies, this compact gauge leverages an intelligent 3-axis digital gyro sensor to automatically detect blade height and horizontal level baselines. Featuring a sharp, auto-inverting backlit display, it allows technicians and hobbyists to lock down flawless tracking configurations in any lighting environment.

Key Features:

  • Advanced Gyro Angle Tracking: Built-in digital electronic gyro automatically senses the horizontal level and rotor plane to provide continuous pitch readouts.
  • Wide Blade Range Compatibility: Specially designed jaw mounting mechanism seamlessly fits main rotor blade lengths from 250mm to 800mm and chord widths from 20mm to 75mm.
  • Auto-Inverting Backlit Screen: Crystal-clear digital LCD screen turns upside down automatically based on tool orientation, guaranteeing stress-free visibility during upside-down checks.
  • Zero Calibration & Angle Locking: Integrated memory functions allow operators to delay angle resets, lock current metrics, or establish a relative zero baseline.
  • Energy Efficient Power Architecture: Automatic power-saving shutdown routines turn the display off after 3 minutes of zero movement to conserve internal battery cells.
  • Ultra-Lightweight Pocket Profile: Weighing only 38 grams including batteries, it securely clips onto delicate composite blades without dragging down the blade grip or warping calibration angles.

Product Overview

Achieve absolute flight stability, minimize vibration tolerances, and eliminate tracking flaws with the TL90 Digital Pitch Gauge Inclinometer. Manual plastic pitch cards are difficult to read and open to human perspective errors. The TL90 eliminates this guesswork by introducing real-time digital angle reading down to a ultra-fine 0.1 degree resolution threshold.

Capable of scanning a full plus or minus 90 degree operational field, this device functions not only as a helicopter blade tester, but also as a steering gear swing arm analyzer, micro-level meter, and structural angle tool. Powered by dual standard button cells, this instrument provides commercial drone operators and RC model builders with an accurate setup framework.
